Wideband/narrowband integrated meter-reading device

The utility model relates to a wideband/narrowband integrated meter-reading device which comprises a wideband power line carrier communication module, a narrowband power line carrier communication module, a meter-reading/maintaining RS485 interface and an infrared interface. The device can manage a carrier electric energy meter or an electric energy meter with the RS485 interface, is mainly characterized in that the upstream data and the downstream data of a collector can be transmitted through the power line carrier communication, and the meter-reading device can perform the mete-reading management on the electric energy meters with different communication interfaces, so that the complexity of a meter-reading system is reduced, and the popularity is improved. Power lines are used as the communication carriers of an upstream passageway and a downstream passageway, so that plenty of additional wiring can be eliminated, the device cannot be artificially damaged, and the device is less susceptible to the lightning stroke and the overvoltage.
